Hi actually I figured out the issue with this one from a forum on google's support pages:

* A disabled button is displayed in the following cases:
* 1. If merchant id or merchant key is not set
* 2. If there are multiple shipping options selected and they use different
shipping tax tables
* or some dont use tax tables
* 3. The cart is empty
My case was #2 -- I had two different shipping options with two different tax tables - which worked fine for zencart checkout but not GC.

But now I'm on to a new problem! Read below... :)
